Anglo Swiss Resources Completes Metallurgical Study for 93% Gold Recovery at the Kenville Gold Mineadmin
Anglo Swiss Resources Inc., announces that G&T Metallurgical Services Ltd. of Kamloops, British Columbia has completed a Metallurgical Scoping Study for the company’s Kenville Gold Mine Project near Nelson, British Columbia. G& T Metallurgical Services is an integrated mineral process research and development company with laboratories for sample preparation, mineral processing testing, mineralogical analysis and chemical analysis.
The objectives of the Kenville Property study were to: 1) assay the gold, silver, copper, and lead grades of six submitted representative mineralized rock samples, 2) prepare a composite by combining the six submitted samples, 3) determine the grindability of the composite, 4) test gravity concentration techniques to the composite sample, 5) test how the composite responds to the standard flotation technique, 6) determine possible concentrate upgrading techniques, and 7) develop a simplified mineral processing flowsheet.
The results indicated that the composite feed grade from the six submitted samples is 18 g/tonne gold, 0.94% lead, and 0.25% copper. (See News Release March 23, 2009) Approximately 70% of the gold came from the two underground Jewelry Box stope samples. The standard flotation technique recovered 98 percent of the feed gold into a concentrate of 155 g/tonne gold, 355 g/tonne silver, 12 percent lead, and 2.5 per cent copper. By combining the gravity and flotation techniques, the result was a 93 percent gold recovery with an average concentrate grade of 200 g/tonne, 18 percent lead and 3.3 percent copper.
The grindability testing indicated the mineralized material is moderately hard at a workload of 14.6 kWh/tonne. Once the composite was primarily sized to –100 mesh (-150 microns), the weighted average of the three gravity concentration tests resulted in a 53 percent feed gold recovery at a concentration grade of 530 g/tonne.
From the simple flowsheets developed from this scoping work, Anglo Swiss Resources has completed the preliminary design work for its Kenville Milling Facility, which includes selecting the remaining required equipment, and to determine both capital and operating costs. The Mill is scheduled to be operational by the end of the third quarter of 2009.
